Definitions

  • each aspirator In an application where there are several different concentrates, a separate aspirator can be used for each concentrate. Each aspirator is connected by tubing to each concentrate reservoir to conduct concentrate from the reservoir to the aspirator. A single gun means provides water flow for the several aspirators. The benefit of this arrangement is that each concentrate has a dedicated aspirator that is configured to provide optimum dilution and flow.
  • the present invention provides a convenient means to modify a dispensing system in the field to maximize performance and can be used in virtually any dilution system.
  • Another feature of the present invention is the use of identification means on the corresponding components of the apparatus 100.
  • the labels on the concentrate packaging 113, the aperture in the front panel 108, the aspirator 40, the storage jugs 111, and the spray bottles 103 are all color-coded and/or have corresponding labels. This enables a user to quickly and easily attach the appropriate aspirator to the correct concentrate container. This minimizes the chance of contamination and minimizes the likelihood that a particular cleaning product will be used at an improper dilution ratio, thus enhancing the effectiveness of the cleaning product. This feature also results in a cost savings for the user, in that waste of the cleaning product is eliminated when the proper dilution ratio is maintained.
